초록 | The polycrystalline CdZnTe:Cl thick films which have high resistivity about 5 × 109 Ωcm are grown by thermal evaporation method.The leakage currents of as-deposited CdZnTe layers are still too high to operate as medical applications. The blocking layer of Schottkytype was formed on the stoichiometric surface of polycrystalline CdZnTe layers to suppress the leakage current of polycrystallineCdZnTe X-ray detectors. The polycrystalline CdZnTe Schottky barrier diodes with indium contact exhibit the low leakage current(14 nA/㎠) at 40 V due to its high barrier height (φb = 0.80 eV). In X-ray image acquisition with Schottky-type linear array polycrystallineCdZnTe X-ray detector, we have obtained the promising results and proved the possibility of polycrystalline CdZnTe for applicationsas a flat panel X-ray detector. |
